Is Lenovo any good over Dell and Asus?

I'm planning to buy a Lenovo laptop. Model is Lenovo Ideapad Z510. But my friend who already owns 2 Lenovo laptops told me that there's a overheating issue with Lenovo laptops.

So I'm bit confused if I should go with Lenovo or other brands.

I'm a working professional and so I use 8 the laptop almost 8-10 hours a day.
Configurations I was looking for is

I7 - 4th generation
8GB RAM
750GB or 1TB Hard disk

So please do suggest me if I should go with Lenovo or some other brand.

Lenovo makes the best and most reliable windows laptops around. They are followed fairly closely by HP, Asus, and Samsung. For a variety of reasons, my nearly 30 years of working with laptops has convinced me not to consider other brands. The two most solid and reliable lines of machines are the Lenovo Thinkpads and the HP Elitebooks. Those are the business grade machines and are absolutely top tier hardware.

All laptops have problems with overheating under heavy use, particularly with the graphics processor. Laptops are carefully engineered, balancing weight and power consumption against a variety of other factors. They are designed to cool adequately under normal use in a "normal" environment. Serious gaming is generally not considered normal use unless you purchase a gaming machine. Those start at about $750 for the most basic gamers, $1000-$1250 for an okay gamer, and $1500+ for a good-great gamer.

A computer is not an investment. It is an expense, a cost, just like a car. It is a tool you use to do work which wears out and has very little value a few years later - far less than you paid for it.

Budget is an important issue in choosing a Laptop and if you are going to use it for 8 hrs or more than a good one is needed. If the price is right I will go for Lenovo and from my experience they are really value for money.Dell, Asus both do good Laptops so it's a matter of taste and money. Regarding overheating this is a common problem on Laptops, I use Hp and had the same issue and never had an effect on my Laptop just keep a look at the temperature and avoid using on beds or sofas, so it's can have a good ventilation from the bottom part.

In general, asus win

unless you are talking alienware dell… You didn't say how much budget you have nor asus and dell you preffered

is this okay Asus N750JV?
